upgrade: Upgrade tool rector does not work on Cakephp 3.8.12

Hi,

I use CakePhp 3.8.12, php 7.4, win 10 and installed the upgrade tool in another folder than my cakephp folder.

I ran the up bin\cake upgrade rector --rules cakephp40 ..\relative\path\to\cakephp with debug mode because it got stuck at 0/412 => 0%

Here is the error I got :

Applying cakephp40 Rector rules
File "C:\webserver\www\cakephpUpgradeTool/vendor/autoload.php" is about to be loaded in "AutoloadIncluder::includeCwdVendorAutoloadIfExists()" on line 98"

During composer install --no-dev I also has this error : Class Cake\Composer\Installer\PluginInstaller is not autoloadable, can not call post-autoload-dump script

And for windows user, it doesn’t work when a folder has a space in its name.

Hope there is something to be done !

Thank you very much
